Almost certainly your data was cribbed from a loan application. That's how the scammer ''leads'' are generated. These PDL thugs are busy today. See my reply in another thread, active about the same time as your entry:

I received a call saying that they were a law firm and they were trying to collect for a unsecured loan with a company that I have no knowledge of. I think they may have gotten my information from an payday advance I did online. They called my job because I kept asking and wanted to check the company out first. They crossed the line by calling my job.
